Speaker Porting Through Backlit Keyboard Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In portable devices like laptops, speakers often require porting to reach users effectively, but traditional methods involving large holes or grills on the enclosure can muffle sound and compromise backlight illumination, especially when porting through a backlit keyboard.
Innovation Solution
A system and method for porting a speaker through a keyboard module and backlight module using a port path that extends from the speaker to the outer surface, with a first portion in the enclosure adjacent to the edge of the modules and a second portion at the periphery of a key, allowing sound transmission without visible holes or grills, thereby maintaining illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large holes or speaker grills are used for speaker porting, then sound transmission is improved, but the appearance is compromised and backlight illumination is reduced
Solution Approach 1:
The port path is divided into multiple segments: a first portion through the enclosure and a second portion through the keyboard module. This segmentation allows sound to travel through different paths, avoiding the need for large holes in the enclosure while maintaining sound transmission effectiveness.
Solution Approach 2:
The keyboard module acts as an intermediary structure that facilitates speaker porting without requiring large holes in the enclosure. The port path through the keyboard module's periphery provides a mediator path for sound transmission that preserves both appearance and backlight illumination.
2Reliability
If large holes or speaker grills are used for speaker porting, then sound transmission is improved, but the appearance is compromised
Solution Approach 1:
The port path is segmented into portions through different structures (enclosure and keyboard module), eliminating the need for visible large holes or grills on the device surface while maintaining effective sound transmission through the distributed path.
Solution Approach 2:
The keyboard module serves as an intermediary that enables speaker porting without compromising the device's appearance. By routing sound through the keyboard module's periphery, the solution provides a mediator path that preserves the clean surface appearance while achieving effective sound transmission.
3Reliability
If speaker porting is done through the enclosure, then sound transmission is achieved, but the porting structure becomes complex
Solution Approach 1:
The keyboard module is given a dual function: it serves both as the input interface and as part of the speaker porting structure. This multi-functionality eliminates the need for separate porting structures, reducing overall device complexity while maintaining effective sound transmission.
Solution Approach 2:
The speaker porting function is merged with the existing keyboard module structure. By combining these functions, the invention eliminates the need for separate porting structures and large holes in the enclosure, thereby reducing device complexity while achieving effective sound transmission.
